Patented June 30, 1931 UNITED STATES PATENT OFFICE ALBERT LINDSAY DOERING, OF GERMANTOWN, PENNSYLVANIA, ASSIGNOR TO J. S. THORN COMPANY, OF PHILADELPHIA COUNTY, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA METALLIC WINDOW STRUCTURE Application filed December 30, 1929. Serial No. 417,380.

My invention is applicable to what are known as double hung windows, including a jamb frame in which two sash frames are mounted to reciprocate parallelwith each other, and relates particularly to means for maintaining the sash frames in weather-tight relation with the jamb frame without interfering with the freedom for reciprocation of said sash frames. Such means include flanges projecting from the sash frames parallel with the plane of the latter and fitted in corresponding grooves in the jambframe, and a removable weathering strip detachably connected with the j amb frame between the sash slideways in the jamb frame. Said sash flanges are provided with means for detachable connection with chains or other flexible connectors from the sash frames to sash counterbalance weights and, as hereinafter described, the construction and arrangement are such that removal of a section of said weathering strip affords access to the connections between the sash frames and the counterbalancing means, which means are concealed when the weathering strips are in their normal position in the jamb frame.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings, Fig. I is a front elevation of a typical embodiment of my invention in a double hung window structure.

Fig. II is a fragmentary vertical sectional view of the structure shown in Fig. I, taken on the line II, II, in Fig. I, with adjoining portions of the building structure.

Fig. V is a fragmentary sectional View taken on the line V; V, in Fig. I.

Fig. VI is a fragmentary sectional view taken on the line VI, VI, in Fig. I.

Fig. VII is a fragmentary elevation of the left hand side of the lower sash style shown in Fig. III.

Referring to Fig. I; said window structure includes the window frame comprising a lintel 1, opposite j ambs 2 and 3, and a sill 4 which are connected in rigid relation. The upper sash 6 and lower sash 7 are mounted to reciprocate in said window frame and are respec tively counterbalanced by weights 8 and 9.

Referring to Fig. II, said lintel 1 is conveniently formed of two pieces of sheet metal 11 and 12 which have their edges interlocked, as indicated at 13. Said lintel piece 11 is pressed to form the finish molding 15 upon the outer face of the frame, and the finish molding 16 upon the inner face thereof, and is pressed to form the two grooves 17 and 18 adapted to receive flanges 19 and 20 projecting upwardly from the top rail 22 of the upper sash 6.

Said top rail 22 of the upper sash 6 is conveniently formed of two pieces of sheet metal 23 and 24; said flanges 19 and 20 being in unitary relation with said piece 23 and being of inverted J -shape to receive the flange 25 on said rail piece 24. Said top rail piece 23 also has the downwardly extending flange 27 forming a reces for the glass 28 which is seated in putty 29 or other suitable cement.

Said upper sash 6 has the bottom or meeting rail 31, conveniently formed of a single piece of sheet metal bent upon itself at its opposite edges to form the drip flange 32 at the outer edge of said sash and the weathering flange 33 at the inner edge of said sash. Said rail 31 is also'bent intermediate of its edges to form the shoulder 35 to support the glass 28, and to form the channel 36 adjoining said weathering flange 33 to hold the packing 37 which may be a piece of asbestos fabric, adapted to seal the joint between said bottom rail 31 of the upper sash and the top rail 39 of said lower sash 7.

Said top rail 39 is conveniently formed of two pieces of sheet metal 40 and 41. Said piece 40 is bent upon itself at its outer edge to form the weathering flange 43 adapted to fit in airtight relation with the packing 37 in the channel 36 of the bottom rail 31 of the upper sash 6, when the meeting rails of said sashes 6 and 7 are in the closed position shown in Fig. II. The opposite, and inner, edge of said top rail piece 39 is bent to form a finished bead 45 which interlocks with said a weather-tight joint between said sill and '63 on the other bottom rail piece 65.

piece 41, as shown. Said top rail piece 39 is bent intermediate of its edges to form the channel 47 to hold the edge of the glass 48 which is seated in putty or other suit-able cement 49 in said recess. Said top rail piece 41 has flanges 51 and 52 at its respectively opposite edges, closely fitting in the recess 53 in said rail member 39. The block 55 in said recess 53 has screw sockets 56 for reception of sash fastening means, and reinforces said top rail 39 of the lower sash 7 intermediate of its width.

The bottom rail 57 of said lower sash 7 is also conveniently formed of pressed sheet metal, including the outer piece 58 which is bent intermediate of its edges to form the flange 59 to retain said glass 18. The opposite edges of said bottom rail piece 58 are inwardly turned to form the J-shaped flanges 60 and 61 which are of dill'erent extent, as shown, to fit the slope of said sill 1. Said flanges 60 and 61 receive the flanges 62 andl Sait piece 65 is bent to form the hollow flange 66 engaging the flange 67 of the flexible resilient weathering strip 68 which is adapted to yieldingly bear upon the sill 4, and thus make the sash 7.

As shown in Fig. II, said sill 4 is conveniently formed of a single piece of sheet metal having its opposite edges inwardly turned at 70 and 71 to reinforce it and incidentally engage cemcntitious material 72 on the building wall 73 which supports the window structure aforesaid.

Referring to Figs. III, IV, and V, it is to be understood that each of the amb frames 2 and 3 is formed of two pieces of sheet metal 76 and 77 which are detach ably connected as hereinafter described. Said piece 76 has its opposite edges 7 8 and 79 bent to J-shaped and is pressed intermediate of its edges to form the outer finish molding 81 and the inner finish molding 82. The other jamb piece 7 7 has its opposite edges 84. and 85 respectively fitted in said J-flanges 78 and 79 of the piece 76, and is bent intermediate of its width to form vertically extending grooves 86, 87, 88, and 89, and is normally held in rigid relation with the jamb piece 76 in the position shown, by vertical series of screws 91 which ertend between said grooves 87 and 88 and are in threaded engagement with respective yoke bars 92 which have inwardly turned ends 93 and 94 respectively overlapping said J flanges 78 and 79, as shown. Each of said jamb members 2 and 3 is also provided with removable weather strip sections 96 which are detachably held in rigid relation with said jamb frame plate 77 by screws 97. Each of said weathering strips 96 is channel shaped, having opposite parallel flanges 98 and 99 extending-into said grooves 87 and 88,

and each preferably with a spring weathering cap 100, formed of sheet bronze.

Said jamb grooves 86 and 87 are respectively adapted to receive, in weathering relation, the flanges 101 and 102 of the opposite side styles of the upper sash 6. Each such member is conveniently formed of a single piece of sheetmetal 103, and said flange-101 is reinforced at its edge by bending said sheet metal 103 back upon itself, as indicated at 105. I also prefer to provide each such reinforced portion of said sash flanges with a spring weathering cap 106, preferably formed of sheet bronze, and as indicated in Fig. III. Said flange 102 is J-shaped at its edge to embrace in its bight the flange 98 of said weathering strip 96, in weathering relation therewith. Each such plate 103, of the sash 6, is bent intermediate of its width to form a flange 108 to support an edge of the glass 28 which is embedded therein in cement 29, as above described.

Said grooves 88 and 89 in the jambs 2 and 3 are similarly adapted to receive, in weathering relation, the flanges 109 and 110 on the opposite side styles of the lower sash 7. Each such member is conveniently formed of a single piece of sheet metal 111. Said flan e 110 is reinforced at its edge by bending said ,sheet metal back upon itself, as indicated at 112. I also prefer to provide each such reinforced portion of said sash flanges with a spring weathering cap 113, preferably formed of sheet bronze, and as indicated in Fig. III. Said flange 109 is J-shaped at its edge to embrace in its bight the flange 99 of said weathering strip 96, in weathering relation therewith. Each such plate 111 of the sash 7 is bent intermediate of its width to form a flange 115 to support an edge of the glass 48 which is embedded therein in cement 49, as above described.

Each of the opposite weathering flanges 102 of the upper sash 6 carries, concealed within the-respective grooves 87, respective hook plates 117 adapted for detachable engagement with the ends of respective chains 118 which extend over pulleys 119 which are journaled .on shafts 120 in pulley housings formed of two angularly bent plates 121 and 122 which are secured upon the outer face of the respective jamb member 77, in the position indicated by dotted lines in Fig. III. The opposite ends of said chains 118 are respectively connected with counterbalance weights 8 which arcsuspended for Vertical reciprocation within the respective jamb members 76.

Each of the opposite weathering flanges 109 of the lower sash 7 carries, concealed Within the respective grooves 88, respective hook plates 125 adapted for detachable engagement with the ends of respective chains 126 which extend over pulleys 128 which are ournaled on shafts 129 in said pulley housing, in the position indicated by dotted lines in Fig. III. The opposite ends of said chains 126 are respectively connected with counterbalance weights 9 which are suspended for vertical reciprocation within the respective jamb members 76. In order to prevent swaying of said weights 8 and 9 into frictional contact with each other, I prefer to interpose the partition web 132 between them, which web is formed of a sheet of metal having its outer edge slit transversely to form oppositely bent flanges 133 by which it is rigidly connected with the inner face of said jamb member 76, conveniently by spot weldmg the same.

Although single panels of glass 28 and 48 may be mounted in said sashes 6 and 7, as above described; I prefer to divide the area and reinforce large sashes with munt-in bars 135, as indicated in Figs. I and VI.- Said bars are conveniently formed of rolled steel with T-shaped flanges 136, and of less width and consequently less conspicuous than ordinary muntin bars. As indicated in Fig. VI, said bars hold cement 137, such as indicated at 29 and 49, and inwhich the edges of the glass panels 138 and 139 are embedded.

I prefer to provide each of the sash styles aforesaid with respective hook plates such as indicated at 125 in Fig. VII, and including two hooks connected by a bar fitted within the bight of the respective J flange 109, or 102; said hooks projecting through slots 141 in such flange and said bar being spot welded to the flange, as indicated at 142. Said hooks are so space-d as to fit within respective links in the chain 126 or 118 as indicated. Said hooks are so proportioned that the chains may be readily manually connected and disconnected with respect thereto when the local section of the weathering strip 96 is removed from the jamb.

As shown in Fig. III, the double or so-' called Dutch edges of the sash weathering flanges 101 and 110 are bent so as to extend in symmetrical relation with the other, single thick, portions of those-flanges and thus minimize the area of the flange which may come into contact with the opposed weathering surfaces of the groove in the jamb, with the advantage that the frictional resistance to the vertical movement of the sashes is reduced to the minimum, and that advantage is enhanced by covering those flange edges with the films of bronze 106 and 113 which afford antifriction surface for sliding contact with the opposite walls of the grooves in the jamb in which said sash weathering flanges slide.

An important advantage of the form of sash styles above described is that it permits glazing with putty, as distinguished from glazing with. strips of metal secured by screws, which is the usual practice. In order to glaze with putty, it is necessary to have a considerable surface of the style extending transversely to the glass for engagement with the putty. Altho such a surface might be afforded by making the styles L-shaped (leaving off the sash flanges 101 and 110), such construction would leave a space between the outer surface of the style and the inner surface of the jamb, (where the marks 103 and 111 appear in Fig. III,) which would not only be unsightly but would admit the weather, between the upper sash and the j amb. Therefore, it is not only advantageous to provide the sashes 6 and 7 with the extra flanges 101 and 110 to cover the crevices which otherwise would be left between the styles and the amb but to afford a double weathering joint for each sash. Therefore, I desire to broadly claim a window sash with such double weathering flanges, and particularly such a sash with means upon one of its weathering flanges to engage a sash counterbalance.

However, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
